Dear Nisha,
It totally depends on you….in the old course, there are 8 papers…plus you can appear for all the 8 ..i.e 4 modules in the June 2014 attempt.
Agreed that the old course will cease to exist after June 2015 attempt, but then according to me, you should not think of taking 4 attempt naa…be positive in your approach…And if God Forbid you take more attempts, you will get an exemption for the papers you cleared, in the new course…
And as far as learning goes, you have all your life to do so…Qualification is more important…if you go for the old one, you can showcase that you cleared CS Final in the First Attempt as against a minimum of 2 sittings for the new one…
I suggest…go for the old one onle
All the Best
